En-route radar
The en-route radar (French for "air road radar ") is an air traffic control radar especially for route control of air surveillance. These radars mostly work in the L-band with a range of up to 240 nautical miles or 450 km.
They depict air traffic outside of the special airport areas in which airport surveillance radar devices (ASR) are used. The antennas rotate relatively slowly at a speed of 4 to 6 revolutions per minute (ASR devices work at 12 to 14 revolutions per minute). They are installed on high concrete towers in order to prevent people from being in dangerous proximity to the main lobe of the transmitted energy and from being damaged by the electromagnetic waves ( non-ionizing radiation ) emitted .
En-route radars are primary radars , which features a modern Mode S-capable secondary radar are coupled. The SRE-M6 (MSSR Nordholz) en-route radar in Nordholz is remote-controlled from Bremen Airport and monitors the north-west of Germany and the entire North Sea . The subsequent areas are the Deister and Schmooksberg stations . Each of these six systems nationwide has a detection radius of around 145 NM (270 km)
